Notes:
• The Y cable from J7 connects to the pump and a data I/O power cable, so the system can connect
to a PC for setup and to transmit data, and to externally power the 25plus.
•Auxiliary sensors that draw more than 1 amp, even momentarily, must be connected to
J3 or J6. Refer to integration of high current-draw sensors for details.

Section 3 Replace batteries
WARNING
Explosion hazard. If the batteries are not installed correctly, explosive gases can be released. Make
sure that the batteries are of the same approved chemical type and are inserted in the correct
orientation.
WARNING
If the user thinks that a sensor has water in the pressure housing: Disconnect the sensor from any
power supply. Put on safety glasses and make sure that the sensor is pointed away from the body
and other people. In a well ventilated area, use the purge port (if the sensor is so equipped), or very
SLOWLY loosen the bulkhead connector to let the pressure release.
WARNING
If the user thinks that the alkaline batteries have leaks, pressure may have built up inside of the
pressure housing. Follow ESD protocols to release internal pressure. Put on safety glasses and
protective gloves and make sure that the sensor is pointed away from the body and other people. In
a well ventilated very SLOWLY loosen the bulkhead connector to release the pressure. Keep away
from heat, sparks, flame, and other sources of ignition. Do not smoke.
English 7
CAUTION
The pressure housing contains Electrostatic Discharge (ESD) sensitive parts and assemblies that
are susceptible to damage from ESD. Follow ESD protocols:
• Put on protective eye wear before you open the pressure housing.
• Any electrostatic charge on the body of the human operator must be released before the
pressure housing is opened: put a hand on a grounded surface, or better, wear a grounded
antistatic wrist strap.
• At a minimum, wear short-sleeved antistatic clothing, such as cotton, or better, wear an antistatic
smock for this service activity. Do not wear a sweater, fleece or polyester-based clothing.
• At a minimum, use a workstation with a wood or metal tabletop, or better, a tabletop that
dissipates static. Do not use a workstation with a synthetic or polymeric-based tabletop.
N O T I C E
Blue Moly™ and Dow Corning®4 lubricants are electrically conductive. Keep away from electrical components.
The 25plus uses 12 Duracell® MN1300, LR20 D-cell alkaline batteries.
Remove the batteries if the 25plus will be stored for a long period. Store batteries at a temperature
between 5 °C and 30 °C.
1. Remove the battery end flange (opposite the end with connectors):
a. Clean the outside of the end flange and the housing. Make sure all parts are dry.
b. Turn the end flange counter-clockwise to remove it.
c. Use a lint-free cloth or tissue to remove any water from the O-ring surfaces inside the
housing.
d. Make sure to protect the O-ring from damage or contamination.
2. It is not necessary to remove the battery pack from the housing, but to do this:
a. Use a 9/64 inch hex wrench to loosen the captured post that attaches the battery pack in the
housing.
b. Pull the handle up and then pull the battery pack from the housing.
c. Turn the battery pack over and remove the batteries.
d. Install new batteries with the + terminals up. Refer to the marks on the side of the battery
pack.

3. Install the cover on the battery pack again:
a. The cover fits into the battery pack only one way. The opening next to the USB mark must
align with the USB connector in the battery pack.
b. Tighten the cover until there is no gap between the bottom O-ring and the battery pack
housing.
4. If the battery pack was removed from the pressure housing, use the banana plug sockets on the
bottom plate of the battery pack to verify that the battery voltage is approximately 19.5 volts.
5. Install the battery pack in the pressure housing if it was removed.
a. Make sure there is no water on any surface.
b. The O-rings must be pristine. Apply a small quantity of Parker Super O-Lube on any new O-
rings, then carefully install the new ones.
6. Carefully put the end flange in to the pressure housing and tighten into position. Use a wrench if
necessary.
